Not surprisingly, Beyoncé and Blue Ivy have quickly become the mother-daughter pair to watch for their sartorial choices. Even though Blue is only two months old, she's already shown an affinity for adventurous footwear. Meanwhile, Bey has taken to wearing flats--specifically, slippers--post-pregnancy. So, for an outing in NYC yesterday, Global Grind pointed out that Beyoncé and Blue decided to make an adorable fashion statement and wear coordinating cat and mouse slippers: Blue's mouse slippers are Little Marc Jacobs and Beyoncé's wearing those genius Charlotte Olympia kitty flats we're obsessed with but can't afford. Fortunately, Blue's shoes cost a reasonable $66.
